Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

NRC engineers share their expertise at the University of Puerto Rico
Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

In the process of electron beam and plasma interaction, the angular magnetic field produced by the electron beam affects the physical parameters of the plasma. In this paper, first, the Thomson ionization coefficient under the condition of cross field is derived. Second, based on a magnetohydrodynamics method, the axial distribution of plasma density in the positive column of low-pressure glow discharge under the magnetic field is deduced, and the effect of the angular magnetic field on glow discharge plasma is studied. Finally, the above results are verified by numerical simulation. The results show that when the pressure is 10 Pa, the plasma density first increases and then decreases with the increase of magnetic field. When the pressure is 0.1 Pa, the plasma density decreases with the increase of magnetic field.
